For a stock or mild cam it's good stuff. 15-40 Delo and Shell Rotella T is good too. 2010 Black Challenger SE <> 3.5 V6 Custom Shift Knobs www.flameball.com Check It Out

Diesel oils, motor cycle oils, some racing oils and the heaviest grade of Mobile 1 (15W-50?)have it. My choice is Rotella T + STP because its readily available and cost effective.

Mobil,Penz,Quaker state..?? In my 76 F150 I've been using he Valvoline VR1 racing oils as it is high zinc content but not sure how much. Broke the engine in with it no problems with a new flat tappet cam. Maybe someone here has the numbers? It isn't much more than regular dino oil. Running the 20W50 stuff. Edit: Found this post on BobIsTheOilGuy forum: http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1271805 Looks like 1300 ppm zinc and 1200 ppm phosphorus for the VR1 oils.

Delvac diesel oil used to have high zinc content but it has been dropping from the levels shown in my 2007 analysis. Your life is not my fault. My life is none of your business. Speech is free only if you agree with those in control.
